<h2>Why is this an issue?</h2>
<p>Each source file should start with a header stating file ownership and the license which must be used to distribute the application.</p>
<p>This rule must be fed with the header text that is expected at the beginning of every file.</p>
<p>The <code>headerFormat</code> must end with an empty line if you want to have an empty line between the file header and the first line for your
source file (<code>using</code>, <code>namespace</code>…​).</p>
<p>For example, if you want the source file to look like this</p>
<pre>
' Copyright (c) SonarSource. All Rights Reserved. Licensed under the LGPL License.  See License.txt in the project root for license information.

namespace Foo
{
}
</pre>
<p>then the <code>headerFormat</code> parameter should end with an empty line like this</p>
<pre>
' Copyright (c) SonarSource. All Rights Reserved. Licensed under the LGPL License.  See License.txt in the project root for license information.
